Presentation

minimal degreeμ(G) = 24
transitive degreeμt(G) = 64

A minimal faithful permutation representation — 3 generators on 24 points:

(1,2,4,8,5,6,3,7)(9,10)(11,18,20,23,19,24,21,14)(12,16)(13,15)(17,22);(2,6)(3,4)(9,11)(10,14)(12,21)(13,19)(15,23)(16,18)(17,24)(20,22);(1,3,5,4)(2,7,6,8)(10,15)(11,19)(16,17)(20,21)
